This brass-rimmed monocle hums with quiet energy, its green-tinted lens flickering faintly with arcane circuits. Built for artillerists who value precision and efficiency in combat. While wearing these glasses you gain the following benefits: 

Tinker’s Shot:  When your Eldritch Cannon hits a creature with an attack, you can choose to enhance the strike. Roll an Intelligence check (DC 12):

• Success: The cannon deals an additional 1d8 force damage.
• Failure: No additional effect.

You can use this feature 3 times per long rest.

Quick-Tune Mending:  You can cast Mending as a bonus action, but only when targeting: Constructs, or Objects you created using Magical Tinkering or Eldritch Cannon.  Repair grants 1d4 + Int modifier hp to the target.
